Reading larger xlsx files is too slow

[DeaJason]

The plug-in is easy to use, but its performance is poor, and it is not friendly to large files. It takes 4-5 minutes for a 4M file. Do you consider improving the performance of reading large files?

I entered this repository exactly through this problem. I hope the creator or another maintainer can resolve it as soon as possible.

You can use isolates to run the number crunching on a different thread, while keeping the UI thread smooth.
